Hi, I am an American Board Certified Neurologist with experience in treating all neurological and other medical conditions and I am very glad to help you with your health concerns. The previous expert has opted out. I have experience in diagnosing and managing urinary tract conditions.
Coming to the discussion;
Your symptoms are mainly suspicious for a kidney stone, more than UTI.
Initially you had intense chills along with fever which did not recur – this pattern implies the stone most likely moved from its initial position, and possibly moved to the bladder
Since then you have been experiencing discomfort while passing urine of varying degrees and this appears due to the stone still stuck somewhere, most likely in the urinary bladder – which is what is causing persistent symptoms
The presence of blood in the urine initially correlates with the stone, rather than UTI
I guess you are not seeing blood now and this could be because the stone has moved to the bladder, also there may be microscopic bleeding which is not seen by naked eye
You seem to have recurrent UTI, so kidney stone possibility needs to be ruled out
Your recent symptoms do raise suspicion for stones (bleeding, initial chills etc)
Your symptoms are most likely from the stone rather than from UTI, this can explain why you are not improving with antibiotic Bactrim
You may try to undergo 2 important tests asap;
1) Urine analysis, even if you are on antibiotic the urine test can still tell whether you are having infection or not. Culture is still possible considering you are not responding to Bactrim. Also urine can reveal any crystals/stone particles – if stone is indeed the culprit.
2) Ultrasound of KUB (Kidney, Ureter, Bladder), OR X ray of this region too can help, but ultrasound is safer so to start with ultrasound. If ultrasound or X ray does not help then further investigations are necessary
While Quinolone antibiotics like Cipro (Ciprofloxacin) etc can cause certain serious side effects, but it sounds you did use this antibiotic before, and seem to have tolerated it well before, so it may not harm you this time too. However if you do not want to take chance with Cipro then Cephalosporin group of antibiotics or Penicillin group of antibiotics like Amoxacillin/Augmentin etc too can be considered. These antibiotics are certainly safer than Quinilone antibiotics like Cipro
UTI should not present with blood so early in the illness, that too actual blood, this is most likely a stone presenting like UTI, or stone + UTI.
Feeling like still need to pee again & again even after emptying the bladder on the back ground of prior passing blood in the urine and symptoms not responding to a good antibiotic like Bactrim all point towards a stone more than UTI. You may have secondary UTI too, but the primary issue appears to be a urinary tract stone, most likely stuck in the bladder and causing persistent symptoms, so instead of only focusing on switching the antibiotic please also consider getting proper diagnosis with urine analysis, stone workup (like ultrasound, or X ray etc to start with). If antibiotic is going to be changed then a Cephalosporin group antibiotic or penicillin group antibiotic like Augmentin/Amoxacillin can be a good choice in your case.
